It should be clarified that the industrial pigments involved in this case are fundamentally different from legal food additives. China's National Food Safety Standard for the Use of Food Additives (GB 2760) implements a strict approval system for allowed food additives, and all additives listed in the standard undergo scientific risk assessment. As long as the production enterprise uses it in a standardized manner, its safety is fully guaranteed. Article 34 of the Food Safety Law clearly stipulates that the production and operation of food using non food raw materials, or food containing chemicals and other substances that may harm human health other than food additives, or food produced using recycled food as raw materials, are prohibited. Industrial pigments are chemical substances that are explicitly labeled as' inedible '.

Food safety is no small matter, illegal additives are a red line that must not be crossed. From kindergarten to internet famous food, from milk powder to catering, behind every illegal addition incident, there is a serious threat to consumer health. Only by implementing a three pronged approach of corporate self-discipline, strict supervision, and public oversight can we build a solid defense line for food safety and truly ensure the safety on the tip of the tongue. In terms of food heavy metal regulation and testing， The standards such as GB 5009.268-2025 "Determination of Multielements in Food" stipulate the method of ICP-MS detection of heavy metals in foodICP-MS has demonstrated unparalleled advantages in the detection of heavy metals such as lead in food due to its sensitivity and multi-element analysis.

In this incident, in addition to the issue of harmful substances in food, blood lead testing cannot be ignored. Blood Lead Level (BLL) is an assessmentRecent levels of lead exposure and assessment of poisoningKey indicators. Especially for children, due to underdeveloped metabolism and excretion abilities, the amount of lead ingested per unit weight is relatively higher, and lead is more likely to pass through the blood-brain barrier, causing irreversible damage to brain development. Therefore, rapid and accurate determination of lead content in the blood is the cornerstone of early detection, intervention, and treatment of lead poisoning. The "Consensus on the Application of Mass Spectrometry Technology in Clinical Trace Element Detection" formulated by the Clinical Mass Spectrometry Laboratory Medicine Professional Committee of the Laboratory Physicians Branch of the Chinese Medical Association in 2019 pointed out that currently, ICP-MS is widely used as the mass spectrometry technology for clinical trace element detection.

This incident should become an opportunity to improve the child health protection system, as lead poisoning in children is a preventable problem. By improving the standard system, strengthening source control, and building a solid health defense line for children, every child can stay away from the threat of 'invisible killers' and grow up healthy in a safe environment.
